IPC: B41J11/48
Filed: 1985-10-28
Abstract: PURPOSE:To contrive better switching between a slip paper and a continuous form paper, by a construction wherein a paper-feeding roller is pressed against a platen when a lever is set to the slip paper side, and the roller is separated from the platen when the lever is set to the continuous form paper side.

IPC: B60C23/06
Filed: 1994-10-05
Abstract: PURPOSE:To exclude a wrong signal for improving the detection of a reduced pressure tire during the whole running time by actuating a tire alarm indicator according to an error value which is computed from the specified group of anglar velocity signals of each wheel speed sensor and then revised. CONSTITUTION:The sum of signals of an another group is subtracted from the sum of signals at the diagonal positions of the angular velocities C1 to C4 of each wheel to obtain error value DEL', namely 0.05 to 0.5, during normal running from an expression I, and C1 to C4 are mutually compared to detect that the decision computation of the reduced pressure tire is in progress of processing. In addition, during constant running under such a condition as the tire pressure is reduced by 0.6 bar in order, and fixed pressure is kept at the other portions, the error value DEL' FAC (W) of each wheel W equipped with a reduced pressure tire is computed by an expression II, and the wheel factor FAC(W) of each wheel is computed by an expression III. In addition, DEL' is divided by the FAC(W) of the reduced pressure tire to compute a standardized revised error value STDDEL, and when the value STDDEL is 0.05 to 0.5, a tire alarm indicator displays that a specified tire is reduced in pressure.

Abstract: PURPOSE:To enable regulating the light output of each light emitting element and controlling light output with high precision, by putting, periodically in order, light emitting elements of an array light emitting device except one element, in pausing state, and controlling the light output of the light emitting element in light emitting state, in a specified value previously determined. CONSTITUTION:By a driving signal from a controlling part 1, the driving of laser diode elements L2, L3 except a laser diode element L1 is interrupted, during an interval from time Tn to time Tn+DELTAT. At this time, only the laser diode element L1 emits light, and a photo detecting part 15 is irradiated with only the output light of the laser diode element L1. The incident light from the laser diode element L1 is converted into a current signal proportional to the light intensity, and delivered to the controlling part 1, which compares a current signal from the photo detecting part 15 and a current flowing condition signal previously given, and so controls the driving current I, that the difference is decreased. After that, light output adjustments of the respective laser diode elements L1-L3 are repeated at the respective adjusting time points, and the driving current is set to a fixed value. The above operation is repeated for all array laser devices 14, and the light output is controlled.
